Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer crushers, specifically a self-cleaning fertilizer crusher. Background Technology

[0002] A fertilizer crusher is an agricultural machine used to crush solid fertilizers (such as organic fertilizers and chemical fertilizers) into finer particles. The main purpose of this machine is to increase the effective surface area of ​​the fertilizer, making nutrients easier for the soil and plants to absorb, while also helping to improve the uniform distribution of fertilizer and the convenience of application.

[0003] Patent CN221452721U discloses a pulverizing device for bio-fertilizer production and processing, relating to the field of fertilizer production and processing technology. The device includes a pulverizing body, a control panel fixedly mounted on its surface, a fertilizer input device fixedly mounted on its top, a drive motor fixedly mounted on its top, a main support platform fixedly mounted on its surface, and a main base fixedly mounted on the bottom of the support platform. This device, by incorporating a fertilizer guide platform, solves the problem of existing pulverizing devices easily getting stuck in the inner groove, causing blockages and affecting the guiding effect. Through this structural combination, the pulverizing device, via a guiding mechanism, can guide the fertilizer into the crushing mechanism during use, effectively preventing fertilizer from getting stuck in the inner groove.

[0004] However, the above-mentioned pulverizing device still has the following problems in actual use:

[0005] The feed hopper of a crusher is the first point of contact for fertilizer entering the crusher. During use, some fertilizer may remain on the inner wall or in the corners of the feed hopper, especially organic fertilizers or fertilizers containing sticky components. If these residues accumulate over time, they may clog the feed hopper, affecting feeding efficiency. However, current crusher feed hoppers do not have a self-cleaning mechanism, which means that workers need to spend time cleaning the feed hopper separately after each use of the crusher, which is time-consuming and labor-intensive. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides a self-cleaning fertilizer crusher that can automatically clean the inside of the feeding hopper after the crusher body is used.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning fertilizer crusher, comprising a crusher body, a discharge pipe installed on one side of the lower end of the crusher body, and a feed hopper installed on the upper end of the crusher body. Two support blocks are fixedly connected to one side of the upper end of the feed hopper. A rotating mechanism is connected inside the two support blocks. A shielding component is connected to the output end of the rotating mechanism. The other end of the shielding component is located directly above the feed hopper and matches the size of the feed hopper. An air supply mechanism is connected to one end of the crusher body near the feed hopper. An air blowing component is connected to the output end of the air supply mechanism. The other end of the air blowing component passes through the shielding component into the interior of the feed hopper.

[0008] Furthermore, the rotating mechanism includes a motor and a transmission rod. The outer wall of the motor is fixedly connected to one side of one of the support blocks. The output shaft of the motor is fixedly connected to one end of the transmission rod. The other end of the transmission rod passes through both support blocks and is rotatably connected to the inner walls of both support blocks. The part of the transmission rod located between the two support blocks is connected to the shielding assembly.

[0009] Furthermore, the shielding assembly includes a rotating block and a top plate. One end of the rotating block is sleeved and fixedly connected to the outer wall of the transmission rod, and the other end of the rotating block is fixedly connected to the side wall of the top plate. The bottom surface of the top plate abuts against the upper surface of the feed hopper, and the size of the top plate matches the feed hopper.

[0010] Furthermore, the air supply mechanism includes an air pump and a main air pipe. The outer wall of the air pump is fixedly connected to the upper surface of the crusher body, and the output end of the air pump is fixedly connected to one end of the main air pipe. The air pump, the main air pipe, the air blowing assembly, and the feed hopper are internally connected.

[0011] Furthermore, the air blowing assembly includes an annular pipe and several branch pipes. One end of each branch pipe is fixedly connected to the end of the main air pipe away from the air pump. The other end of each branch pipe passes through the top plate to the inside of the feed hopper and is fixedly connected to the annular pipe. Several air jet holes are opened through the outer wall and bottom surface of the annular pipe. The main air pipe, branch pipes, annular pipe, air jet holes and the inside of the feed hopper are connected.

[0012] Furthermore, a hydraulic rod is fixedly connected to the upper surface of the top plate. The output end of the hydraulic rod passes through the top plate to the inside of the feed hopper and is fixedly connected to a connecting plate. Both ends of the connecting plate are fixedly connected to the inner wall of the annular pipe.

[0013] Furthermore, the maximum pushing distance of the hydraulic rod is not less than the depth of the feed hopper.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This self-cleaning fertilizer crusher has an air supply mechanism installed on the outside of the crusher body and an air blowing component installed inside the feed hopper. After the crusher body crushes the fertilizer, the air supply mechanism and the air blowing component can clean the feed hopper and the inside of the crusher body by blowing air.

[0016] 2. This self-cleaning fertilizer crusher has a rotating mechanism on one side of the feed hopper of the crusher body, and a shielding component is connected to the rotating mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1-3 A self-cleaning fertilizer crusher includes a crusher body 1, a discharge pipe 2 installed on one side of the lower end of the crusher body 1, and a feed hopper 3 installed on the upper end of the crusher body 1. Two support blocks 4 are fixedly connected to one side of the upper end of the feed hopper 3. A rotating mechanism is connected inside the two support blocks 4. A shielding component is connected to the output end of the rotating mechanism. The other end of the shielding component is located directly above the feed hopper 3 and matches the size of the feed hopper 3. An air supply mechanism is connected to one end of the crusher body 1 near the feed hopper 3. An air blowing component is connected to the output end of the air supply mechanism. The other end of the air blowing component passes through the shielding component into the interior of the feed hopper 3.

[0023] This utility model discloses a self-cleaning fertilizer crusher, which is structurally similar to existing organic fertilizer crushers, such as the crushing device for bio-fertilizer production and processing disclosed in patent publication number CN221452721U. Figures 1 to 3 As shown, when using the self-cleaning fertilizer crusher of this utility model, first turn off the power of the crusher body 1 to ensure that the crusher body 1 is not working. Then turn on the rotating mechanism. After the rotating mechanism is started, the output end controls the shielding component to rotate. When the shielding component rotates to be flush with the feed hopper 3, the opening of the feed hopper 3 is sealed, so that no dust will overflow from here during subsequent cleaning. Then turn on the air supply mechanism. The output end of the air supply mechanism supplies air to the air blowing component. The air blowing component will send the gas into the sealed feed hopper 3 and the crusher body 1, and then blow air into the inside of the feed hopper 3 and the crusher body 1. During the blowing process, the fertilizer powder adhering to the inner wall will be discharged from the discharge pipe 2. Before this, it is only necessary to set a collection bag outside the discharge pipe 2 for collection.

[0024] It is important to note here that:

[0025] 1. The self-cleaning described above is only a simple cleaning after each use of the crusher body 1. Its purpose is to remove residual materials in the feed hopper 3 and the crusher body 1. This can prevent the materials from being difficult to clean after drying and reduce the difficulty of starting up the next time. After the crusher body 1 has been used many times, it needs to be thoroughly cleaned. At this time, it is still necessary to clean it according to the original cleaning method, such as using a high-pressure water gun with cleaning solution.

[0026] 2. An air extraction device (such as a blower) can also be installed at the outlet of the discharge pipe 2. This way, when the air blowing component blows air into the feed hopper 3 and the inside of the crusher body 1, the blower can suck away the floating fertilizer dust, thereby increasing the cleaning effect. The blower is a mature technology, so it will not be described in detail here.

[0027] like Figures 1-3 As shown, the rotating mechanism includes a motor 5 and a transmission rod 6. The outer wall of the motor 5 is fixedly connected to one side of one of the support blocks 4. The output shaft of the motor 5 is fixedly connected to one end of the transmission rod 6. The other end of the transmission rod 6 passes through the two support blocks 4 and is rotatably connected to the inner walls of the two support blocks 4. The part of the transmission rod 6 located between the two support blocks 4 is connected to the shielding assembly.

[0028] More specifically, when it is necessary to control the rotation of the shielding component, simply turn on the motor 5. The output shaft of the motor 5 will then rotate the transmission rod 6, which in turn will cause the shielding component to rotate.

[0029] like Figures 1-3As shown, the shielding assembly includes a rotating block 7 and a top plate 8. One end of the rotating block 7 is sleeved and fixedly connected to the outer wall of the transmission rod 6, and the other end of the rotating block 7 is fixedly connected to the side wall of the top plate 8. The bottom surface of the top plate 8 abuts against the upper surface of the feed hopper 3, and the size of the top plate 8 matches that of the feed hopper 3.

[0030] More specifically, when the transmission rod 6 rotates, the rotating block 7 connected to it will rotate together, and the rotating block 7 will rotate with the top plate 8, thus sealing the opening of the feed hopper 3 through the top plate 8.

[0031] like Figures 1-3 As shown, the air supply mechanism includes an air pump 10 and a main air pipe 11. The outer wall of the air pump 10 is fixedly connected to the upper surface of the crusher body 1, and the output end of the air pump 10 is fixedly connected to one end of the main air pipe 11. The air pump 10, the main air pipe 11, the air blowing assembly and the feed hopper 3 are internally connected.

[0032] More specifically, when it is necessary to clean the inside of the feed hopper 3 and the crusher body 1 by blowing air, simply turn on the air pump 10. The output end of the air pump 10 sends the gas into the main air pipe 11, and then it can enter the inside of the blowing assembly through the main air pipe 11.

[0033] like Figures 1-3 As shown, the air blowing assembly includes an annular pipe 14 and several branch pipes 12. One end of each branch pipe 12 is fixedly connected to the end of the main air pipe 11 away from the air pump 10. The other end of each branch pipe 12 passes through the top plate 8 to the inside of the feed hopper 3 and is fixedly connected to the annular pipe 14. Several air jet holes 15 are provided through the outer wall and bottom surface of the annular pipe 14. The main air pipe 11, branch pipes 12, annular pipe 14, air jet holes 15 and the inside of the feed hopper 3 are connected.

[0034] More specifically, the gas inside the main air pipe 11 will preferentially enter several branch pipes 12, and then pass through the top plate 8 via several branch pipes 12 before entering the annular pipe 14 together. Finally, it will be ejected from several jet holes 15. Since the jet holes 15 are located on the outer wall and bottom of the annular pipe 14 respectively, they can blow air onto the inner wall of the feed hopper 3 and the crusher body 1, thereby blowing off some of the residual fertilizer dust until it is discharged from the discharge pipe 2.

[0035] like Figures 1-3 As shown, a hydraulic rod 9 is fixedly connected to the upper surface of the top plate 8. The output end of the hydraulic rod 9 passes through the top plate 8 into the interior of the feed hopper 3 and is fixedly connected to a connecting plate 13. Both ends of the connecting plate 13 are fixedly connected to the inner wall of the annular pipe 14. The maximum pushing distance of the hydraulic rod 9 is not less than the depth of the feed hopper 3.

[0036] More specifically, by setting up the hydraulic rod 9 and the connecting plate 13, when the annular pipe 14 is blowing air to clean the inside of the feed hopper 3 and the crusher body 1, the annular pipe 14 can also be controlled to rise and fall until it descends into the inside of the crusher body 1, so as to clean the inside of the crusher body 1 more effectively.

[0037] It should be noted that in this case, both the shunt pipe 12 and the main air pipe 11 are flexible hoses that can be extended, such as using an accordion hose.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
